The inflator that deploys the driver's frontal air bag in the event of an accident may rupture and spray metal fragments onto vehicle occupants. This can increase risk of serious injury or death.
An electrical connection problem at the body control module can result in various concerns related to application of the brake pedal.
1) Exterior brake lights not working as expected
2) Difficulty disengaging the cruise control
3) Moving the shifter out of park without pushing the brake pedal
4) Disabling of the traction control, electronic stability control, and braking assist systems
The shift cable may fracture and not indicate the proper gear as selected by the driver. This could allow a vehicle to roll when it is expected to be in "Park".
Power steering assist could be lost unexpectedly. Should this occur, steering ability would be maintained but would require much more effort.
